Abstract
Residual stresses formed in surfaced shafts and influencing their cyclic loading resistance have been experimentally studied. It is shown that subsequent mechanical treatment of the shafts (roll burnishing, ultrasonic shock peening, explosion treatment) induces compressive stresses in the surface layer
Keywords: surfacing, shaft model, residual stresses, roll burnishing, ultrasonic shock peening, calculation, experiment
